Jasmin is a twelve-year-old Adelaide girl of Aboriginal descent. Her parents, both doctors, have volunteered to work in the Middle East for a year, so Jasmin will stay with her aunt and uncle in tropical Darwin for that time. The prospect is both very exciting and saddening, but to help with the sadness of missing her parents, Jasmin will be allowed to get a dog - her very first one.
At the local animal shelter, she meets and chooses Reg - an Australian sheep dog - who turns out to be not only super smart but also very much devoted to her.
Lots of new experiences and adventures follow; including a challenging adjustment to a new school environment, a near lethal encounter with a hungry crocodile and an equally dangerous encounter with gangsters stealing radio-active materials. But there is also lots of fun to be had - with new friends, parties, sailing, and horse riding - always with Reg in attendance of course!
